My invention relates broadly to vending machines and more particularly to a machine for delivering commodities such as milk, butter, cheese, bread and other food products and beverages, by the insertion of a coin in a slot to permit the withdrawal of the package to be delivered.

One of the objects of my invention is to provide a vending machine of simplified construction which may be readily manufactured for installation in factories, schools, pleasure resorts and in various sections of residential districts of towns to deliver to customers food products upon the insertion of coins in slots provided therefor.

Another object of my invention is to provide a simplified construction of vending machine in which a revolving cylinder member is provided for the selection of the package which it is desired to deliver, which member may be actuated by an external crank arm only after the insertion in the machine of coins in the proper amount, with means for locking the machine against unauthorized tampering at all othertimes. I

Still another object of my invention is to provide a construction of vending machine in which the working parts are disposed within a casing forminga support for the machine and the articles to be delivered carried in a display rack position substantially at 25 to the supporting base in order that the articles which are tobe vended may be clearly visible to the customer.

a have described my invention with, particular reference to a vending machine for bottles of milk, but it will be understood that other food products may be delivered by the machine and that no limitations as to the use of the machine are intended.

My invention will be more fully understood from the specification hereinafter following by reference to the accompanying drawings, in which:

Figure 1 is a front view of the vending machine; Fig. 2 is a vertical cross sectional view on line 2-2 of Fig. 1 through the machine; Fig. 3 is a cross sectional view on line 83 of Fig. 2 showing the operating parts in so locked position; Fig. 4 is a cross sectional 1925. Serial No. 46,327.

view of the parts illustrated in Fig. 3 but showing a coin inserted in the slot for re1easingthe lockingmechanism permitting the r0- ration of the delivering member for the delivery of a package; Fig. 5 is a cross sectional View of the parts illustrated in Fig. .4 showing the locked mechanism entirely removed from the path of the revolvable member allowing complete rotation of the revolvable member for the delivery of the desired article; Fig. 6 is a fragmentary cross sec tional view through the machine taken on line 66 of Fig. 2; Fig. 7 is across sectional view taken on line 7 7 of Fig. 3; Fig. 8 shows a partial side elevation of the machine with the casing broken away to clearly indicate the working parts therein; Fig. 9 is a perspective view of the revolvable cylindrical member; and Fig. 10 is a perspectiveview of one of the pairs of end guide plates which I 7 provide on the revolvable member. Referring to the drawings in more detail, reference character 1 indicates a supporting casing for the vending machine. Reference character 2 shows the vertical display casing which extends upwardly from the supporting base substantially at an angle of 25 from the supporting base which contains the bot- 'tles of milk or otherarticles of merchandise 6, which are arranged to slide vertically'beg0 tween partition members 3 and '4 visible through glass panel 5. The cabinet portion 2 terminates in a lower extension 7 of a size 7 into which the bottle of milk 6 may be readily deposited and withdrawn by the customer through the aperture provided therefor as represented in Figs. 1 and 2. A revolvable member 8 is journaled in the lower end of the display cabinet 2 at points 10 and 11, the journal 11 being supported in a bracket 12 so which is secured to the display cabinet 2. The revolvable member 8 has a pocket 9 therein of a shape and size sufficient to receive the article or package which is to be vended. In the construction illustrated the pocket 9 is of a size to receivea bottle of milk 6 and deliver the same into pockets 7. The revolvable member 8 is actuated by a crank arm 14 extending'from the front of the machine in a convenient position to be grasped by the cus-' 10.0

protrusion 17 and 18 at one side of the periphery thereof. A pivot member 21 is provided for j ournaling locking bars 22 and 23 in a position where the ends 22 and 23 extend within the inturned edges of the flange m'embersl'f, and 18 while the ends 22" and23 extend beneath the coin slots 24 and 25. The locking bars 22 and 23 are normally v balanced in such manner that ends 22 and 23 gravitate toward the reduced portion of revolvable member 8 with the ends thereof in abutment with the ends 22 and 23 of the locking bars 22 andf23. By reason of the pall and ratchet mechanism 19 and the rotation ofthe revolvable member 8 can only take place in counterclockwise direction, suchrotation being normally prevented by the abutment of the locking bars against the protrusion 16. In Fig. 3 the machine is il- V as ' further raising the locking bar 22 freeof.

5 the coin is illustrated in position-26 still engagement with theabutment 16 on the revolvable lmember, enabling the revolvable 'member to freely turn in its journal, for delivering one bottle of milk6. I provide two coin slots 24 and'25 for coins of different he vendedi The movement of the locking bars 22 and 23 is oscillatory and in order to prevent tampering with the machine by locking the entire machine through diiferent angles in the attempt to gravitate the bars 22 and 23 out ofposition, I'may provide any form of safety device positioned upon pivots beneath the locking bars .22 and 23 to be brought into position when the machine is rocked into a'difl'erent plane. The employment of this form of safety device prevents the operation of the machine when the l machine is tipped.

It will be observedthat the operation of the machine is positive and the-construction and operation of parts extremely simple. The construction illustrated has been practically employed and operated giving extremely satisfactory service. It will be observed that packages of cubical or rectangular contour may be employed without departing from the spirit of my invention. I desire that it be understood that further modifications may be made and that I intend no limitations upon the invention other than those imposed thereon by the scope of the appended claims.
